A fighter from the FDLR rebel group, which is being hunted by the Rwandan and Congolese armies, watches over civilians ordered to destroy a bridge at the village of Peti in eastern Congo, February 7, 2009. Rwanda and Congo are undertaking a joint operation to flush out the FDLR, a Hutu extremist group that includes former Interahamwe killers who committed the 1994 Rwandan genocide before fleeing into the lawless wilds of eastern Congo, where they have been at the root of 15 years of unrest that has killed some five millions people, most from hunger and disease.
